Summary
This wildlife pond was constructed in 1988 with the primary purpose of supporting fish and wildlife habitats. The dam, standing at a height of 10 feet and length of 250 feet, has a storage capacity of 400 acre-feet and serves as a vital resource for the local ecosystem.
With a drainage area of 6 square miles and a maximum discharge of 670 cubic feet per second, Steen Wma plays a crucial role in regulating water flow in the Minnesota River tributary. The dam, classified as a buttress-type structure, has a controlled spillway to manage excess water and prevent flooding. Despite its low hazard potential and satisfactory condition assessment, the risk assessment for Steen Wma indicates a very high level of risk, emphasizing the importance of continued monitoring and maintenance to ensure its long-term functionality and safety.
As a key component of the state's water resource management infrastructure, Steen Wma provides valuable support for wildlife conservation and habitat preservation in the region. Its strategic location in Big Stone County, Minnesota, underscores its significance in the broader ecosystem and highlights the interconnectedness of water resources and climate resilience efforts. With proper regulation, inspection, and enforcement procedures in place, Steen Wma serves as a model for sustainable water management practices in the face of evolving environmental challenges.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
